HOW DOES DENSITY AFFECT THE MELTING POINT OF WATER?

Chemistry
1 answer:
ddd [48]3 years ago
5 0
<span> As a liquid is heated, its vapor pressure increases until the vapor pressure equals the pressure of the gas above it. Bubbles of vaporized liquid (i.e., gas) form within the bulk liquid and then rise to the surface where they burst and release the gas. (At the boiling temperature the vapor inside a bubble has enough pressure to keep the bubble from collapsing.) In order to form vapor, the molecules of the liquid must overcome the forces of attraction between them.<span> The temperature of a boiling liquid remains constant, even when more heat is add.</span></span>

The student repeated the experiment using a higher concentration of acid. The same volume of acid and the same mass of magnesium
Elena L [17]

Answer:

53 cm³

Explanation:

When the student used dilute sulfuric acid, the reaction was complete after 60 s, because no more hydrogen was formed in the next 10 s.

The reaction would go faster if the student used a more concentrated acid, but 53 cm³ of hydrogen is the most that would form.

What is the name for a substance made of billions of oppositely charged ions<br> joined together?
bija089 [108]

Answer:

Ionic substance

Explanation:

An ionic substance is formed when oppositely charged ions link up to form an infinitely large lattice structure that can only be described in terms of unit cells.

Ionic substances may consist of billions of oppositely charged ions. Ionic substances are hard, have high melting and boiling points and do not conduct electricity in the solid state because the ions are not free in the solid state.

However, in solution or molten state, the substance conducts electricity since the ions which are the charge carriers are now mobile.

QUE VENTAJAS TIENE PARA LA PLANTA Y EL CULTIVO LA PERMANENCIA DEL POTASIO COMO CATION MONOVALENTE (K+)?
yarga [219]

Explanation:

Son muchos los beneficios del catión monovalente (K+) en las plantas y cultivos, mencionaremos algunos:

-Interviene en el proceso de apertura y cierre de los estomas; el catión (k+) ayuda a que los estomas puedan realizar correctamente  el proceso de la fotosíntesis es decir  la absorción del dióxido de carbono para producir oxígeno y agua; este proceso ayuda a que la planta pueda fabricar su propio alimento es decir transformar materiales inorgánicos en orgánicos como azúcares y carbohidratos que son aprovechables por la planta para realizar diversas funciones catalíticas como la respiración celular,la fosforilación y la síntesis de proteínas; este proceso también contribuye a que la planta pueda almacenar y retener suficiente agua lo cual ayuda a evitar el estrés hídrico en la planta.

Por lo tanto si la planta tiene una buena concentración de potasio como catión monovalente(k+); es posible que tenga un buen crecimiento y desarrollo radicular ,así mismo la calidad de los cultivos será muy buena,seran cultivos muy nutritivos y saludables. Algunos cultivos que necesitan una alta cantidad de potasio son los cítricos y el banano.
